Abstract Irradiation of yttria-stabilized zirconia (YSZ) was performed by a picosecond pulsed laser to investigate the possibility for multiscale surface patterning. Nanoscale laser-induced periodic surface structures (LIPSS) were successfully generated inside microscale grooves over a large surface area under specific conditions. A thermally induced phase transformation of YSZ was identified after laser irradiation, and this phase transformation was restrained by reducing the laser power or the number of irradiations. Moreover, it was found that the generation of LIPSS greatly changed the surface wettability of YSZ. These results demonstrated the possibility of creating zirconia hybrid patterns with high functionality, which may expand the applications of YSZ in industry.

AbstractCdTe evaporates into Cd and Te atoms under high power, pulsed laser irradiation. The mechanism is different from thermal evaporation where only atomic Cd and molecular Te are formed. The presence of Te atoms is responsible for some unique nucleation processes, such as the epitaxial growth of CdTe on (111) CdTe substrates with either polarity and the enhancement in sticking coefficient in CdTe deposition.
